Adam and Eve had the highest amount of genetic information, but as these groups of people migrated and mated with each other and similar descendants repeatedly (like family members mating). Genetic info is lost, and they develop 'race traits'

So, you can't believe that DNA chain got longer as time went on, but can't show the mechanism by which a DNA strand could pass on incomplete data and still result in healthy off-spring?
Basically, you think everything used to be perfect, and will get worse until you go to heaven.
We think everything used to be crap, but we will make ourselves better until we reach heaven.

Adam and Eve were allotetraploids with fixed heterozygosity at every locus.

I think this just goes to show that the wages of sin include secondary diploidization and population differentiation. At the very least you can expect increases in fixation indices. When Fst = 1.0, Jesus will return in glory!
